# How to setup pre-order products?
How to change **Pre-order** button to **Add to cart** button on product page. Instead of **Add to cart** button it is showing **Pre-order** button, why is that?
Pre-order products are products that will continue to be sold when they are out of stock. With pre-order products, they will be still visible on store and the button "**Add to cart**" of these products will be change to "**Pre-order**" instead of a "**Sold out**" button.
